example 1
[0068]A 62 year old male patient presented with left groin pain. Patient had a history of inguinal hernia repair surgery 5 years prior to presentation. Pain was described as continuous, throbbing, worse with activity and at a level of 7 in a 0-10 Numerical Pain Rating Scale (NRS). Tactile allodynia to light stroking from a foam paint blush was present prior to the intervention. Patient was diagnosed with left groin neuroma based on physical examination finding of palpable neuroma (1.5 cm×1 cm) and paresthesia in the distribution of the genital branch of the left genitofemoral nerve. A CT scan showed no inguinal hernia recurrence. He had previously tried massage therapy, ibuprofen, naproxen, FLEXERIL®, and most recently DEPOMEDROL® and local anesthetic injections 4 times with minimal benefit. Subsequently local tMS therapy was initiated with frequency of 0.5 Hz and 75% amplitude and patient's pre-treatment and post-treatment levels were 4 and 0, respectively. Subsequently local tMS t...

[0069]A 41 year old female initially presented to clinic for botulism toxin injections for chronic migraine treatment but was found to have chronic pain in right foot from plantar nerve entrapment. A neuroma (0.5 cm×0.5 cm) was identified with palpation on physical examination. With deep palpation over the neuroma, the pattern of paresthesia was reproducible along the medial plantar nerve. Prior treatment modalities included cortisone injections, topical capsaicin, lidocaine but no significant change was seen in pain level. tMS treatment was attempted with initial pain score of 5 and post-treatment score of 0. She required repeat treatments at time intervals of four to seven weeks and her pre-treatment pain scores remained 1 to 2 at return visits. The treatment parameters used were frequency of 0.5 Hz, 65% amplitude with 20 pulses per train and average of 20 trains. She is now able to function as a full time veterinarian with barely noticeable pain in her foot.

[0070]A 51 year old female with history of Crohn's disease and multiple abdominal surgeries presented with right lower quadrant abdominal pain. She was diagnosed with abdominal nerve entrapment with initial pain score of 5. Two neuromas (1.5 cm×1.25 cm) and 1.5 cm×1.0 cm) were identified with palpation. Paresthesia could be elicited with palpation over the neuroma. She received tMS treatments with frequency of 0.5 Hz and amplitude of 60% at incisional scar and right lower quadrant abdominal region. Initially she was treated every 2 weeks and later her treatments were scheduled every 4-6 weeks. Overall her average post-treatment pain score ranged from 0 to 2.
